v r I Application filed March 5, 1900. Serial No. 7,259. (No model.)

To a whom it may concern.-

Be it known that 1, JOHN H. GREEN, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri,haveinvented a certain new and useful Gasometer, of which the followingis such afull, clear, and exact description as will enable any oneskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawing, forming part of thisspecification.

The object of my invention is to so construct a gasometer that an outletwill be provided for the gas'to prevent leakage into the room containingthe gasometer either by an abnormal rise in the gasometer or by havingthe bell of the gasometer held down against the pressure of the gas.

My invention consists in certain novel fea-,

tures and details of construction, all of which are described in thefollowing specification and pointed out in the claims afiixed hereto.

The accompanying drawing, which illustrates one form of gasometer madein accordance with my invention, is a vertical central section.

1 represents the body of the gasometer,'-

which is provided with a bell 2. The bell 2 is of the usualconstruction, except that it is provided at its upper end with a sleeve3, thus leaving an annular space 4 for the'reception of water or othersuitable liquid to vary the height of the bell, and consequently thepressure of the gas. The bell 2 is provided with a top 5.

The gasometer 1 is provided with a bottom 6 and a false bottom 7, andthe space between the bottom 6 and false bottom 7 is divided into twochambers 8 and 9 by means of a partition 10. The partition 10 isprovided at its lower edge with one or more openings 11 to allowcommunication of the water in the chambers 8 and 9. Projecting upthrough the false bottom 7 to near the top of the gasometer 1 is a pipe12. The pipe 12 is surrounded by a pipe-13, secured to the top 5 of thebell 2. The pipe 13 is provided near its upper end with openings let.Surrounding the pipe 13 is a pipe 15, also secured to the top 5 of thebell 2 and projecting downwardly.

The pipe 15 terminates some distance above the lower end of the pipe 13.Formed in the lower end of the pipe 15 are openings 16.

17 is a pipe which connects at one end with the pipe 12 and at the otherend with a chamber 18, formed on the side of the gasometer 1.

19 is a bent pipe, one end of which connects with the chamber 8 and" theother end of which terminates near the bottom of the chamber 18.

20 is an L-shaped pipe, the lower end of 'which connects with thechamber 18 and the upper end of which terminates at or near the top ofsaid chamber.

21 is an escape-pipe which extends upwardly from the chamber. 18.

22 is a pipe leading from the chamber 8 in the bottom of the gasometerto near the top of the bell, and 23 is a similar pipe leading from thechamber 9 to near the top of the bell.

24 is a service-pipe which leads from the chamber 9 to the point wherethe gas is to be consumed. V

In the operation of my gasometer the space between the body 1 and bell 2is filled with water in the usual manner. The chambers 8 'and 9 are alsopartially filled with water, so

as to leave a space between the water and the false bottom 7, in whichthe gas collects.

' From the chamber 8 the gas passes upwardly through the pipe 22 intothe bell 2 and thence down through the pipe 23 into the chamber 9 andout through the service-pipe 24. As the pressure of the gasometerincreases the bell 2 will be raised. As soon as the pressure decreasesthe bell will fall. In case too large a quantity of gas is generated andthe bell of the gasometer is raised to an abnormal height the pipe 15will be drawn out of the water. The gas can then pass up through theopenings 16 into the pipe 15 and thence through the openings 14: intothe pipe 12. From the pipe 13 the gas passes through the pipes 12 and 17to the chamber 18 and thence up through the. escape-pipe 21 to the air.If by any means the bell 2 should be held down and prevented from risingwhen an abnormal pressure is generated, the gas would pass out throughthe pipe 19 into the chamber 18 and ICO thence through the exhaust-pipe21 into the air.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

1. In a gas-machine, the combination with a gasometer, of a pipecommunicating with the atmosphere and extending to near the top of saidgasometer, a. second pipe surrounding said first-named pipe and securedto the bell of said gasometer, perforations in said second-named pipe,and a third pipe also secured to the bell of said gasometer andsurrounding said second pipe, said third-named pipe extending over onlya portion of said secondnamed pipe.

2. In a gas-machine, the combination with a gasometer having a falsebottom, of a pipe adapted to be put in communication with the contentsof said gasometer by the abnormal movement of the bell of saidgasometer, an auxiliary chamber adapted to contain water and into whichsaid pipe opens, a pipe provided with a downturned end and leading fromthe space below said false bottom to said auxiliary chamber, a pipeleading from said auxiliary chamber and having an upturned end, and anescape-pipe for said auxiliary chamber.

In testimony whereof I have hereunto set my hand and affixed my seal inthe presence of the two subscribing witnesses.
